Abstract: A traveling grate for a furnace. The grate is formed of plural pipes through which flows a cooling medium, in particular water. The grate also includes plural movable chains. Grate plate guide flanges are arranged laterally on the pipes. The guide plates, which are connected to the chain rest on the guide flanges. The upper strand of each movable chain is guided in an additional chain guide. The lower strand serves to move ash which has fallen through the grate away to a collection station. Due to the heat discharge through the pipes, the heating performance of the grate can be increased or at a given heating performance an elevated life span can be achieved. Fluid which can be heated up in the pipes can be used profitably, for example to preheat boiler heat.

Abstract: A method and means for transporting a quantity of comestibles (preferably at lowered temperatures) where at least continual monitoring of at least the oxygen level of the atmosphere to which the comestible is subjected is carried out. Preferably the carbon dioxide level is also monitored. Automatic adjustment of the oxygen content and carbon dioxide content in response to the monitoring is carried out using a positive infusion of ambient air and the scrubbing of the gas atmosphere to which the comestibles are subjected respectively. Ideally the comestibles are of a respiring nature such as would be the case with plants (whether cut or uncut), fruit and vegetables and they are carried in a container suitable for shipping where a seal of the container sufficient to ensure that less oxygen from the ambient air can diffuse into the container than is required for respiration by said quantity and sufficient to ensure a product of carbon dioxide by said quantity as a result of respiration than can diffuse from the container.

Abstract: The invention relates to a primary pulper turbine for processing recycled paper, of the type having the general shape of an helix. This turbine is formed of a shaft (2) carrying at least two helical disks (3, 4) coaxial to the shaft (2) and having a small pitch. These disks extend over at most 360 DEG  and are spaced from each other along the shaft (2) by a distance of at least 1.5 times the helical pitch of a disk. The turbine carries on its base a set of radially extending fins (6, 7, 8), each one of which is curved into a spiral starting from the shaft (2). Preferably, the slant of the helical disks (3, 4, 5) relative to a plane perpendicular to the shaft (2) is approximately 15 DEG , and the disks are angularly spaced from each other by a same angle approximately equal to 360 DEG  divided by the number of disks, for providing a proper dynamic balance of the turbine. The turbine of the invention is designed so as to have a high separation power for fibers, and to separate contaminants, such as plastics, from the paper pulp, without breaking them up into small pieces. This design lends itself to the building of small efficient primary pulpers, the volume of which may be less than 5 m3, as well as of larger ones.
